CUT-OFF FOR 'CISTERNS.

SPECIFICATION forming part of Letters Patent No. 264,393, datedSeptember 12, 1882,

' Application filed June 17, 1882. (No model.)

To all whom it may concern Be it known that I, GEORGE WILSON, of

Vinton, in the county of Benton and State of' Iowa, haveinvented certainnew and useful Improvements in (JutOffs for Oisterns; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, which lprm a part of this specification, and

i in which- Figure l is aside view of myimproved rainwater cut-off. Fig.2 is a longitudinal sectional view of the same, and Fig. 3 is a verticalcross-section through the plane indicated by line 00 as in Fig. 1.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to rain-water cutoft's for cisterns; and itconsists in the detailed construction and combination of parts of thesame, as hereinafter morel'uly described and claimed.

In the accompanying drawings, the letterA represents thesupply'pipe,which is made with an elbow, B, at its upper end, having aninlet, A, communicating with the gutter, and drainpipes leading from theroof of a building. The elbow B is cut oil obliquely at one end, and hasa hinged door, a through which access may be had to the interior of thedevice-when it is desired to clean or repair the same. The elbow B isconstructed to form a double incline, c c, on its under side, on the topor apex of which is hinged, by its middle, the valve 0, consisting of aflat bottom plate, 0, having two semicircular walls or wings, 0 O one oneach side. The inner end of valve 0 is connected, by a rod, (1, ofsuitable length, to a float, D, which extends down into the cistern orreservoir, the device resting on the top or cover of the same by acircular flanged support or I collar, a. Under normal conditions theweight of rod (1 and its float D will overbalance the outer end of thehinged valve (3, which will rest with its inner end against the inclinec, as shown in full line in Fig. 20f the drawings. In this position ofthe valve water entering the inlet A is led through pipe A into thecistern; but when this becomes full, or the water rises to the float,the buoyancy of this will cause it to rise and push rod d up into thepipe, so as to gradually tilt valve 0 into the position indicated indotted lines. ln this position of the valve water entering at A willescape through the outer open end or mouth of elbow B down the inclinedplane 0, instead of entering the cistern, and this will continue untilthe waterlevel in the cistern has been reduced sulficiently to permitthe float l) to again occupy its normal position.

I am well aware that floats have been used before in this class ofdevices for the purpose of regulating the position of the supply-valveor cut-off; nor do I claim such construction, broadly; but

\Vhat Iclaim as niyimprovement, and desire to secure by Letters Patentot' the United States, is-

In a cistern cut-oft, the combination of the supply-pipe A, constructedwith the elbow B, having door 60 inlet A, and double incline 0 c, hingedvalve 0, having semicircular walls 0 O and rocking on the apex of thedouble incline c 0 within elbow B, rod (1, and float D, all constructedand combined substantially as and for the purpose herein shown andspecifled.

In testimony thatI claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

GEORGE WILSON.
